An Elastic Circular Conducting Loop Expands at a Constant Rate $\varOmega$

An elastic circular conducting loop expands at a constant rate in time.The radius is initially 0.200 m,but then begins to increase 0.018 m every second.The loop has a constant resistance of and is placed in a region of uniform (same everywhere) magnetic field of 0.880 T,perpendicular to the plane of the loop.Calculate the resistance of the loop if magnitude of the induced current 2.4 s after the loop begins expanding is 1.3 * 10^-3 A)

A) 21.9 $\varOmega$
B) 15.0 $\varOmega$
C) 13.4 $\varOmega$
D) 11.4 $\varOmega$
E) 18.6 $\varOmega$
